I use Sheel and/or BP because i have credit cards with them. I have expeiremented a little with them by using their premium grade instead of regular to see if i could detect a diffence in Mileage and performance
Seems like i can always (in my mind) detect an improvement in performance right after i put it in. but as i think back i don't think i ever noticed the difference the next day when i had forgotten about putting it in. I have checked Mileage mecanically and found no improvement in MPG
